The bagua Chinese: 八卦; pinyin: bāguà; lit. 'eight trigrams' are a set of symbols indigenous to China, intended to illustrate the fundamental nature of reality as being composed of numerous mutually opposing forces reinforcing one another. bagua are trigrams—composed of three lines, each either "broken" or "unbroken", which in turn represent yin and yang, respectively. Each line having two possible states allows for a total of 2 × 2 × 2 = 8 trigrams, whose early enumeration and characterization in China has had an outsized effect on the history of Chinese philosophy and cosmology.

The trigrams are related to the divination practice as described within the I Ching and practiced as part of the Shang and Zhou state religion—as well as with the concepts of taiji and the five elements within traditional Chinese metaphysics. The trigrams have correspondences in astronomy, divination, meditation, astrology, geography, geomancy (fengshui), anatomy, decorative arts, the family, martial arts (particularly taijiquan and baguazhang), Chinese medicine and elsewhere.

The bagua can appear singly or in combination, and are commonly encountered in two different arrangements: the Primordial (先天八卦), "Earlier Heaven", or "Fu Xi" bagua (伏羲八卦) and the Manifested (後天八卦), "Later Heaven", or "King Wen" bagua.

In the I Ching, two trigrams are stacked together to create a six-line figure known as a hexagram. There are 64 possible permutations. The 64 hexagrams and their descriptions make up the book. The trigram symbolism can be used to interpret the hexagram figure and text. An example from Hexagram 19 commentary: "The earth above the lake: The image of Approach. Thus the superior man is inexhaustible in his will to teach, and without limits in his tolerance and protection of the people." The trigrams have been used to organize Yijing charts as seen below.

Trigrams

There are eight possible combinations to render the various trigrams:

Relation to other principles

Derivation of the bagua

Book of Changes listed two sources for the eight trigrams. The chapter Xì Cí shàng; 'The Great Treatise I' explains the first source thus:

易有太極， 是生兩儀， 兩儀生四象， 四象生八卦，

Yì yǒu tàijí, shì shēng liǎngyí, liǎngyí shēng sìxiàng, sìxiàng shēng bāguà,

In Change there is the Supreme Polarity,    which generates the Two Modes. (兩儀; Liangyi)    The Two Modes generate the Four Images, (sixiang)    and the Four Images generate the Eight Trigrams.

This explanation would later be modified to:

The Limitless (Wuji) produces the delimited, and this is the Absolute (Taiji). The Taiji produces two forms, named Yin and Yang. The two forms produce four phenomena, named lesser yang, great yang (tai yang also means the Sun), lesser yin, great yin (tai yin also means the Moon). The four phenomena act on the eight trigrams (ba gua), eight eights are sixty-four hexagrams

Another chapter, 說卦; Shuō Guà; 'Discussing the Trigrams', characterizes the 乾; Qián trigram, which represents Heaven, and 坤; Kūn, which represent earth, as father and mother, respectively, of the six other trigrams, who are their three sons (震; Zhèn, 坎; Kǎn, 艮; Gèn) and three daughters (巽; Xùn, 離; Lí, 兌; Duì).

The trigrams are related to the five elements of Wu Xing, used by feng shui practitioners and in traditional Chinese medicine. Those five elements are Water, Wood, Fire, Earth and Metal. The Water and Fire trigrams correspond directly with the Water and Fire elements. The element of Earth corresponds with both the trigrams of Earth and Mountain. The element of Wood corresponds with the trigrams of Wind (as a gentle but inexorable force that can erode and penetrate stone) and Thunder. The element of Metal corresponds with the trigrams of Heaven and Lake.

In feng shui

The bagua is an essential tool in the majority of feng shui schools. The bagua used in feng shui can appear in two different versions: the Earlier Heaven bagua, used for burial sites, and the Later Heaven bagua, used for the residences.

Primordial bagua

In Primordial bagua, also known as Fu Xi Bagua or Earlier Heaven Bagua, In Traditional Chinese medicine this sequence is known as prenatal sequence and is used to understand familial disposition to illness or disease, similar to western medicine's understanding of formative medicine and the study of genetics. The Heaven is in the higher part and the Earth is in the lower part. The Heaven trigram is at the top, the Earth trigram is at the bottom (the South was located at the top in Chinese maps of this period). The Fire trigram is located on the left, and opposite to it is the Water trigram. Thunder and wind form another pair, while being one opposite the other, the first on the bottom left next to fire, while the second is next to Heaven on the top right of the bagua. Mountain and Lake form the last pair, one opposite the other, both in balance and harmony. The adjustment of the trigrams is symmetrical by forming exact contrary pairs. They symbolize the opposite forces of Yin and Yang and represent an ideal state, when everything is in balance.

Later Heaven bagua

The sequence of trigrams in the Later Heaven bagua is attributed to King Wen, also known as the postnatal bagua arrangement in Traditional Chinese medicine that is used to understand physical, emotional and environmental patterns that influences health or disease similar to western medicine's inquiry into functional medical science. In this arrangement Water is placed downwards and Fire at the top, Thunder in the East and Lake in the West. Contrary to the Earlier Heaven bagua, this one is a dynamic bagua where energies and the aspects of each trigram flow towards the following. It is the sequence used by the Luo Pan compass which is used in feng shui and referred to as the manifest pattern analyzes the movement of the qi that practitioners believe affect them.

Western bagua

Feng shui was made very popular in the West thanks to the bagua of the eight aspirations. Each trigram corresponds to an aspect of life which, in its turn, corresponds to one of the cardinal directions. Applying feng shui using the bagua of the eight aspirations (or bagua map for short) made it possible to simplify feng shui and to bring it within the reach of everyone. Western bagua focuses more heavily on the power of intention than the traditional forms of feng shui.

Masters of traditional feng shui disregard this approach, for its simplicity, because it does not take into account the forms of the landscape or the temporal influence or the annual cycles. The bagua of the eight aspirations is divided into two branches: the first, which uses the compass and cardinal directions, and the second, which uses the Bagua by using the main door. It is clear that, not taking into account the cardinal directions, the second is even more simplified.

Bagua map

A bagua map is a tool used in Western forms of feng shui to map a room or location and see how the different sections correspond to different aspects in one's life. These sections are believed to relate to every area or aspect of life and are divided into such categories as: fame, relationships/marriage, children/creativity, helpful people/travel, career, inner knowledge, family/ancestors/health, and wealth/blessings.

In this system, the map is intended to be used over the land, one's home, office or desk to find areas lacking good chi, and to show where there are negative or missing spaces that may need rectifying or enhancing in life or the environment.

For example, if the bagua grid is placed over the entire house plan and it shows the toilet, bathroom, laundry, or kitchen in the wealth/blessings area it would be considered that the money coming into that particular environment would disappear very fast, as if to be 'going down the drain.'

In culture

In traditional Chinese medicine including the profession of acupuncture The principles of Bagua are called the prenatal or early heaven arrangements and the postnatal, later heaven arrangements are used for diagnosis to understand the pathogenesis of disease and illness, to select treatment plans specifically related and tailored to the patients constitution.

In Peking Opera, a role that has Daoist technique or military strategy wears a costume decorated with Taiji and Bagua.

Baguazhang and taijiquan are two Chinese martial arts based on principles derived from bagua.

The principles of Bagua are used in a form of traditional acupuncture where the prenatal, early heaven arrangements and the postnatal, later heaven arrangements are used to select points specifically related or tailored to the patients constitution to treat illness or disease.

The 2004 Philippine horror film Feng Shui and its 2014 sequel, Feng Shui 2, revolves around a cursed bagua mirror that kills those who stare into it.
